I have some Nickel Silver NS106 Temper 3 press formed and turned parts which are tarnished a gold / brown colour. The required colour/finish is silver. I believe you can acid dip the parts to achieve this. Does anyone have any specific experience with this and can give advice on specifics of the acid dipping process required. What causes this tarnished finish in the first place.
